Electronic Musicians, Amateur Radio HAMs Engineers, Technicians and Experimenters If you know the utility of the earlier '555 timer, you'll be WOW-ed by the versatility of this scarce, Voltage Controlled Oscillator (VCO) / Function Generator. Only 3 external parts are needed to create a linear voltage-controlled oscillator with both triangle and square wave outputs. The circuit below shows Pin 5 with a reference voltage supplied by a resistive divider, but the source can come from anywhere, provided it is within the specification limits. Add a simple Triangle to Sinewave Converter TSC #1 or TSC #2: https://linearparts.com/images/566_sine.jpg A third, more sophisticated, Triangle to Sinewave Converter is available in GIF format on request by e-Mail. Request the TSC #3 schematic. Operating V+ is 10 to 24 VDC. Single or dual supplies. Positive or negative ground. Apply a variable DC voltage to the '566 control pin (5), and you can easily sweep a full linear 10:1* decade, frequency tuning range with a single timing Resistor / Capacitor pair (see below). Switch in other R1 / C1 combinations to make a very simple, multiple decade function generator up to 1 MHz. That's twice the FMAX of the NE555! SIGNETICS introduced this part. Its preferred by many experienced users who believe the Signetics outperform other manufacturers' copies (e.g. National), especially in music applications. National Semiconductor copied this part under the P/N LM566 LM566C, and NTE Electronics, Inc. copied this part under their own P/N NTE994. You won't find the genuine Signetics brand NE566 for less, anywhere else! Typical Applications in Communications, Test, Music, Bending: VCO - Linear / Exponential FM Modulation FSK Generator PLL (Phase Lock Loop) Pinball Machine "UFO" Sound Clock Generator Pulse Width Modulation Triangle / Square Wave Function Gen Tunable Noise Generator (music) 455 KHz IF Sweep Oscillator *Want to know more about the NE566? Amazingly, the NE566 can be made to sweep a continuous 1000:1 frequency span with just one fixed timing capacitor. Imagine, continuous linear tuning 20 Hz - 20 KHz or 1 KHz - 1 MHz without switching. A simple op-amp circuit provides the precise voltage control necessary. You set the range with the selection of the timing capacitor. In our lab tests, we used a 0.047µF timing capacitor to achieve a sweep from 23 Hz to 49.5 KHz. That's an amazing 2150:1 ratio! Waveform symmetry does degrade at the very low end however, so if that's critical, a 500:1 or a 100:1 ratio may be more acceptable. Even at a 500:1 ratio, only two timing capacitors (one hardwired, one switched) will allow you to sweep across the range of the NE566 from 4 Hz - 2000 Hz and then 2 KHz to the 1000 KHz, FMAX. Frequency is inversely proportional to the capacitance. Use the 0.047µF as a reference. Double it to halve the frequency, halve it to double the frequency, etc. Voltage, tolerances and circuit layout affect results so it's difficult to calculate exact capacitor values for your desired range. We can get you close with the schematic. From there you'll have to experiment. But it's not hard at all. E-Mail us for the schematic. The NE566 is also used in many vintage arcade pinball machines such as Asteroids to generate those familiar warbling "UFO" sounds. Another use is as a transmitter in a high quality, low distortion Remote FM Speaker System described in AN-146 at https://linearparts.com/documents/an-146.pdf. Finally, for serious DIY MUSICIANS, an excellent book, "Making Music with the 566" by synth guru Thomas Henry shows how to do tricks with the NE566 that even the manufacturer didn't know it could do. We don't stock the book, but it is, without a doubt, the best source available on this part. We highly recommend it. It was out of print for a few years but it's available again. Google the title to find it.
